How can I push my changes to a remote repository?

The complement of git pull is git push, which pushes the changes you have made locally into a remote repository. The most common way to use it is:

git push remote-name branch-name

which pushes the contents of your branch branch-name into a branch with the same name in the remote repository associated with remote-name. It's possible to use different branch names at your end and the remote's end, but doing this quickly becomes confusing: it's almost always better to use the same names for branches across repositories.

1
You are in the master branch of the dental repository, which has a remote called origin. You have changed data/northern.csv; add it to the staging area.
2
Commit your changes with the message "Added more northern data."
3
Push your changes to the remote repository origin, specifying the master branch.
